The former Gunners striker told Radio 5Live of a player who could be on the move in January: “It does look to me like he’s clocked off.

“Sanchez’s attitude is saying a lot about him. If he left in January, the way he’s playing now, I can’t see how that’s going to hurt Arsenal. He’s not playing well enough.

“He’s not putting in a shift. [Philippe] Coutinho wanted to leave [Liverpool]; he put in a transfer request but look at the way he’s playing. Look at the way [Mesut] Ozil is playing.

“People looking in who are potential buyers, what are they thinking about him and his attitude?

“I can’t see Ozil staying but what we’re seeing from him now is the kind of play that we want to see from him."

Sanchez was Arsenal’s top scorer last season, reaching the 30-goal mark across all competitions for the first time in his career, however, he has managed just five efforts this term, while contributing three assists.
